} invention will be understood from the following description consideredin connection with the accompanying drawings formand in which:

a perspective view of the preferred of an adapter of the present inven-Fig. 1 is embodiment tion;

' Fig. 2' is an elevational view, partly in crosssection, showing awasher type shade secured to a bulb by the adapter of this invention;.Fig. 3 is a partial sectional view on an enlarged scale, takensubstantially on line 3-3 of Fig. 2;

44 of Fig. 5;

Fig. 5 is a partial top plan view of Fig. 4; v Fig. 6 is a view similarto Fig. 4 but showing the shade engaged by the adapter ata lowerposition; v .Fig. 7 isapartial elevational, sectional view showing abridge type shade secured to a bulb by the adapter; and a I Fig. 8 is apartial vertical sectional view of a shade secured to a bulb on abridgetype lamp base by the adapter.

,.Like characters of reference refer to like or similarlparts throughoutthe several views.

Referring to the drawings, reference character A designates generally anadapter embodying the present invention. The adapter consistsessentiallyof a bulb engaging portion and a lamp shade engaging portion.The bulb engaging portion comprises two spaced incomplete rings l and IIof resilient wire in substantial alignment with each other. The ends ofthe bulb engaging rings l0 and I I are secured to the lamp shadeengaging projecting from the center portion of the upper edge of therectangular portion and lying substantially in the same plane therewith.The extension I is provided with a laterally extending flange l6. Asshown, the rings I0 and II are secured to the plates M by rolling thelateral edges of the plates around the outer end portions of the ringsinto secure engagement therewith. The ends of the rings I1 and I8 whichextend (Cl. 240-138) v beyond plates tially the same portions l9 andformed if desired.

The rings l0 and H are formed with a diameter such that they will-snuglyengage an electric light bulb in the manner shown in ,Fig. 2. Thedimensions of the plates l4 and the end portions of the rings l0 and IIare such that they will readily and securely engage the inner peripheralportion of bridge or ring type shades and the dimensions of theextensions I 5 are such that they may readily be inserted in therelatively small apertures in a washer type shade and will securelyengage the inner peripheral portions thereof. The rings l0 and II arepreferably made of resilient steel wire with sufiicient resiliency topermit their lower portions to be spread apart in a direction transverseto their planes and to be sprung over an electric light bulb and furtherto permit their end portions, or the plates M, to be moved toward eachother to the extent necessary for them to properly engage the innerperipheral portion of the annulus of any lamp shade, whether bridge,ring or washer type. The rings lll'and Il may be madefrom any materialsuitable for the purpose and may have cross-sectional configurations,other than circularfwhich 'are suitable for the purpose intended. Atsuch times as the adapter is not in engagement with the annulus of ashade, the plates l4 'are'preferably disposed at a distance apart whichis normally greater'than the inside diameter. of any lamp shade annulusto be engaged by the adapter, so that when the plates M are broughttogetherand into engagement with the annulus of a shade, the rings exerta force on the plates tending to force them apart and into secureengagement with the annulus.

Figs. 2 and 3 illustrate the adapter utilized for mounting a washer typelamp shade to a bulb.

l4 are bent outwardly in substan- The bulb B is supported in an uprightposition I the pressure exerted by the resiliency of therings l0 and II.The flanges I6 effectually prevent the adapter from accidentaldisengagement with the washer. After the adapter has been secured to theshade, the

the bulb B and the shade is thereby securely mounted on the bulb. r

rings l0 and II are sprung over mount a ring type shade on a bulb. Thering 28 is secured to the outer shade ring 25 by spokes 21 as with the,washertype shade. :As shownin these figures, the extensions l5 of theadapterare engaged with the inner peripheral portion of the ring 28.

Fig. 6 shows [4 of the adapter so the bulb at a lower Figs. 4 and 5where the ring 28. y

Fig. 7 illustrates the ad'apter'used to-mount a plates, 14 are inengagement with the inner threaded portion 30 of the annulus 3 l' whichis se cured to the outer shade ring 2j5 by thespokes 21'. "If desiredhowever, the adapter maybe disposedwith respect to the shade sothatthe'extensions l5 engage the annulus 3|,in which event the shade will bemounted on thebulb B in a higher position than asshown' in-Fig. '7. aThe 3' of: the rings H! and H prevent adapter with ends I! and'accidental disengagement of th the annulus 3L.

Asshown in Fig. 8, the adaptermay also be utilized to secure a'r'ingltype lamp shade to a bridge lamp. Bulb 3 is threaded in a socket 32supported by theusual bridge lamp arm 33. As shown, the ring 28 isengaged by the extensions H) but may, of courseya's previouslymentioned, be

engaged by the plates l4 if'a lower position of the.

shade with respectto the bulb is desired. With.

this arrangement, the shade is supported with the upper end at the,contact end of the bulb. This arrangement may also I be utilizedto'mount any shade havingv aring to'be engaged by the adapter, which islarge enough to'fit over the bulb socket, on aso-called drop lightthat'is, on a bulb suspended from a cord or rod or theequivalentsupportingmeans. V From the foregoing, itwill be seen that Ihave provided meanswherebyany v V shade may be mounted on an? electriclight bulb which is supported. in any position. And with the exceptionof, the washer v shades maybe mounted on the b lbs attwo dif-- ferentheights. The, advantages ofthe' adapter to sellers of lamps andlampshades-will be ob-- viouS' .1, Q It will be apparent that the'adapterherein disclosed may be modified so as to provide any given height ofthe shade with respectto the bulb on which it is mounted and may also bearrangedso that more than two different heights may be effected. IInasmuch as many modifications'of the former the adapter hereindisclosedmay be made without departing from ,thefprinciple'of theinvention, it will be understoo'dthatf I entertain'no intention to limitthe invention except'by the scope of the claims hereto appended. i, 1
